Tarek,
This should not affect anyone using gcc or g++ on AIX because of this
check just before the lines added by this patch:
elif compiler[:3] == "gcc" or compiler[:3] == "g++":
return "-Wl,-R" + dir
The intention of the patch is to fix linker argument handling with NOT
using gcc, i.e. when using IBM's native AIX compiler.

Yes, I know it will not affect g++ or gcc users,
I was asking that to make sure Sridhar do not intend to make it work on
a system where gcc or g++ are *also* used since they will be picked
prior to this option.
I'll include that patch then.
